1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeTo investigate the diurnal fluctuations of macular vessel density (VD) in primary open-angle glaucoma (POAG) and healthy subjects using optical coherence tomography angiography.

methodsA total of 22 POAG eyes and 15 healthy eyes were included in this study. Macular VD, intraocular pressure, and blood pressure were repeatedly measured from 8 AM to 8 PM at a 2-h interval on a single day.

main outcome measuresthe macular VD measurements, their diurnal fluctuations, including the difference between their maximal and minimal value (max-min) and their coefficient of variation (CV) in superficial capillary plexus (SCP) and deep capillary plexus (DCP). The mixed-effects model was performed to compare the fluctuations between groups.

resultsAfter adjusted age, the diurnal fluctuations of macular VD in SCP and DCP were significantly higher in POAG eyes compared with healthy subjects (max-min: 6.65 ± 3.54%, 3.92 ± 3.63%, respectively; p = 0.037 and CV: 0.06 ± 0.03, 0.04 ± 0.03, respectively; p = 0.003). The fovea VD in DCP of POAG eyes was higher than in healthy subjects (31.52 ± 4.68% and 25.71 ± 3.70%, p = 0.009). However, there was no significant difference between the fovea VD in SCP in two groups (20.97 ± 4.75% and 19.29 ± 4.35%, p = 0.670). The diurnal macular superficial VD measured in most of the participants was lower in the morning.

conclusionsWhether it is a max-min or a CV assessment method, the POAG eyes had more significant diurnal fluctuations of macular VD than healthy controls, suggesting impaired vascular autoregulation in POAG eyes.
